Abstract

PURPOSE: To enable photographic information to be displayed in the finder visual field with a small and simple construction by mounting a sub-prism in the portion which does not shield the photographing field light of the exit face of a pentagonal prism.
CONSTITUTION: The rays from the subject image formed on a focus glass 5 pass through a condenser lens 6 and enter the inside of a prism 1 from an incident face 11, thence they reflect on a roof prism face 12 and a front side reflecting face 13, emit from a rear side exit face 14 and an eyepiece lens 4. A groove part 12 is provided in the portion of this exit face 14 which does not cut off the phtographing field light and a sub-prism 2 is disposed in this groove, then the display information light L from information display means 31, 32 enters the sub-prism from its incident transmittance face 21, is reflected by reflecting faces 23, 24, is emitted from an exit transmission face 22 and is displayed in the predetermined position below the photographing visual field of the finder.
